• Station overload. Weak signals are sometimes captured by stronger
signals when you pass a broadcast tower. A stronger signal may
temporarily overtake a weaker signal and play while the weak station
frequency is displayed.
The audio system automatically switches to single channel reception if it
will improve the reception of a station normally received in stereo.
